We've been waiting on turntable.fm to land on Android for a while now. Well, it's finally here! The music sharing service has been available for a little over a year on desktop machines. The concept is simple: DJs join a room and share songs with an audience that can then vote on whether a song is Awesome or Lame. It's a great concept for sharing music.

The only thing that could make it better is if you could listen to (or DJ!) a room while away from your computer.

Fans of Facebook's mobile app and burgeoning integration with various online services should have something to look forward to in 2012 – founder Mark Zuckerberg, during the first week of a cross-country tour promoting the social networking giant's upcoming IPO, indicated that once the social giant goes public, its goal will be to focus on improving its mobile and advertising experiences.

Zuckerberg indicated that Facebook is "just getting started" with the app, and that the network plans to increase integration with other online apps while working to create a "transformative" ad experience.

Remember Airpush, the ad network that was widely considered one of the most intrusive, irritating methods of advertising in existence (so much so that Lookout released a special app to fight it off)? Well, it looks like the folks at SellARing (pronounced "sell a ring") have come up with something even more insidious.

SellARing's ad network essentially allows associated apps to replace the familiar "ring ring" sound you hear after dialing a number with a selection of 10-second audio ads.

T-Mobile sent out a press release late last night to announce just what they're doing with the consolation prize from AT&T's failed bid to take over the company. Unsurprisingly, the company is using the $4 billion and spectrum licenses to do exactly what they need to stay competitive with other carriers: expand their HSPA+ coverage and, more importantly, roll out LTE.

According to the press release, we can expect T-Mo to continue expanding and improving their HSPA+ for the remainder of 2012:

As part of the company's network modernization effort, T-Mobile also plans to launch 4G HSPA+ service in the 1900 MHz band in a large number of markets by the end of the year.

Remember that problem Galaxy Nexus devices were having on Sprint where owners couldn't get any connection to any data network at all? Well, if you happened to be one of those owners, how could you forget? Worry not, though! Sprint just announced it will be rolling out a fix over "a 1-2 day period."

You'll need to be connected to a WiFi network to do anything (though this shouldn't be new to you if you're affected by this problem).

If you're on the Sprint network, and you're thinking about upgrading to the Galaxy Nexus, you might want to hold off for a bit. Some users in Sprint's forums are reporting that they are unable to connect to Sprint's 3G data network, instead only able to get data via WiFi. Ouch.

Said one user, who attached the above screenshot:

I've attached a screen shot from RF Signal Tracker.

It shows EVDO-A is available and a "Network State" of "CONNECTING"

Every now and then it will get a data connection and the network state changes to CONNECTED, but that will only last for a few seconds. It doesn't matter if I'm in an area with 2bars or 5 bars, same results. I've tried toggling all of the differnt options under Mobile Networks.

Say what you will about Verizon's data plan costs (and we all will), but at least the company works for that money. The LTE rollout continues as Verizon announces expansions to what professionals are calling "a whole lot" of California markets, as well as Reno, Nevada. Most have already had LTE, but if you've ever yelled in frustration when you lose that precious LTE signal while driving down Highway 99 in Fresno, your commute is about to get easier.

It's only been a couple years since the EVO launched as not only the first WiMax phone, but the first "4G" phone (by carrier reckoning). Now, though, Sprint says that not only will there be no more WiMax phones, which we knew earlier, but no more WiMax devices at all. That means hotspots and tablets will also lack any WiMax antennae. Don't worry, though. Sprint has promised 15 LTE devices by year's end.

Sure, Hulu may still be struggling with supporting even a majority of Android devices, but who needs that mess when the CW has an app? Well, yes, people who want to watch shows by any of the other networks, but now all of the CW's top shows are available on (some of) your phones and tablets in their full-episode glory.

It's not quite the complete library experience we've all been hoping for that some shows occasionally get on Hulu or Netflix, but all of the 12 shows available come with 5 episodes each which, we assume, will be the five most recent episodes unless a show is on hiatus, as is the typical custom with most major streaming sources.

Just a few days after allegedly adding its NYC market to the list of 2012 LTE rollout locations, Sprint has evidently begun planning to light up the Los Angeles Metro area by the end of 2012 as well.

Sprint's Los Angeles Metro market currently spans all of Los Angeles County, including Avalon and Santa Catalina. According to S4GRU, Orange County, North LA, Riverside/San Bernardino, San Diego, and Lower Central Valley are included in different markets, and are expected to deploy some time after Los Angeles.
